From the Document: "The Middle East and North Africa (MENA) region is among the world's most water-stressed and vulnerable to climate change. Policymakers' concerns about a changing MENA climate include not only physical and economic impacts but also the potential implications for political stability and security in a volatile region. [...] Projections of various effects of climate change on the largely arid and semi-arid MENA region are available, although regional analyses are often constrained by limited data for MENA and downscaling from global models. Given MENA's geographic span--from Morocco to Iran-- and topographic variation (e.g., mountains, deserts, and deltas), local effects may differ from regional trends."
